To all 'whom it may concern: Be it known that we, RUDOLPH-J. Amon-LT andCHARIJas F. CARLSON, of South Bend, in the county ofSt. Joseph andSt-ate of Indicertain new 'and useful Improvements in Plows; and we dohereby a full, clear, and exact description ofthe invention, such aswill enable others skilled in the art 'to which it appertains to makeanduse the sama This invention relates to plows and more particularly inthe construction of the soilengaging portion or plow bottom whichcomprises the mold-board, share and land-y `side,-on'e object of ourpresent invention` being to provide simple and elicientmeans whereby theshare may be quickly and securely applied to the standard or frog and tothe mold board, or easily and quickly re moved therefrom.

With this and other objects in view the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view o-f a plowembodying our improvements; Fig. 2 is a side elevation; Fig. 3 is asectional view illustrating the connecting means for the share to themoldboard and standard, and Fig. 4 is a separate view of the share.

l represents al standard or frog which may .be convenient-lyv madeapproximately V- shaped in cross Section so as to form two wings ormembers 2, 3-`to which the soilengaging members, constituting the plowbottom, are secured, said plow bottom comprising a mold board 4, a share5 and a land-side 6. The mold board 4 is secured to the wing 2 of thestandard or frog 1, and its forward edge is beveled, as shown at 7. Theshare 5 is also secured tothe wing 2 of the standard audits up er orrear edge is beveled, as at 8, to overlle the beveled forward edge 7 ofthe mold board and thus prevent the latter from sprmging upwardly.

For the purpose of securing the share in place and permitting its easyand quick application or removal, the devicesnow to be described' areemployed.: Several lugs 11 y (preferably three) are securely bolted tothe mold board and project slightly beyond the upper 4beveled edge ofthe share. For the accommodation of some of these lugs (preferablytwo),thel Wing 2 of the standard is provided with holesl3, sothat when theshare is being placed in position as shown in dotted lines in Fig. 8,the hooked-ends 12 of the lugs 11 will pass through said holes andassume'the position shown in full lines, `with the upper faces of ends12 of said` lugs bearing against the inner face of the wine 2 of thestandard and the body portions ofsaid lugs disposed in the holes 13. vFor the accommodation of the `upper lug on the share, a plate 14 issecured to projects beyond the edge thereof,said upper lug bearing' thesame relation,to the plate 14 as the other lugs bear to the fperforatedportions of the standard. The astening devices above described form, ineffect, a hinge connection for the share, enablingthe latter to bereadily dropped or swung into place or lifted or lswung out of position.

When the share has been attached to the standard and moldboard as abovedescribed, it may' be locked in position by a bolt 15 passing throughthe share and the wingv 2 of the standard. The share 5 is constructed,without a rearwardly projecting flange or gunnel heretofore commonlyemployed, and it may therefore be termed a gunnelless share. Instead ofemploying a flange or gunnel, we weld a patch 16.(having a shoulder 17under the forward por# tion of the share, said patch havin a shapesubstantially as indicated in dotte 4lines in Figs. 1 and 4 andextending rearwardly beyond the .lower or forward end of the -standardso as to overlie the latterand extending forwardly approximately to thepoint of the share. The `patch 16 thus ser-ves t'o'thicken the forwardportion of the-share and reinforce or strengthen the same where the-greatest strain and wear are brought to bear.

Th tion of the vshare serves also to effect a raising -of the scouringsurface of the share above the standard so as to presenta straighter orAless concave scouring surface than-.is accomplished with a share havinga.
